Claims (8)

1. Pompe volumétrique avec au moins deux étages pour pomper en phase liquide des gaz de pétrole liquéfiés, comportant au moins deux chambres, chaque chambre comprenant une paroi formée par une membrane, un clapet de non-retour communiquant avec la première chambre pour l'admission du liquide à pomper, un clapet communiquant avec la seconde chambre pour la décharge du liquide pompé, une conduite de transfert s'étendant entre les chambres voisines et pourvue d'un clapet interdisant le retour du liquide de la seconde chambre dans la première chambre, et un moyen de manoeuvre comprenant un piston entraîné dans un mouvement de va-et-vient et équipé de deux surfaces de pression agissant alternativement sur les membranes des chambres, caractérisée en ce que les membranes sont libres de se mouvoir, indépendamment de l'élément de manoeuvre, au cours de l'accroissement de volume de la chambre sous l'effet de la pression du liquide; et en ce que la pompe comporte en outre une conduite de sécurité qui réunit des espaces situés derrière chacune des membranes.
2. Pompe selon la revendication 1, caractérisée en ce qu'en l'absence d'activation extérieure, les membranes présentent une déformation permanente.
3. Pompe selon la revendication 2, caractérisée en ce que la valeur de la flèche de déformation permanente est pratiquement équivalente à la course du moyen de manoeuvre.
4. Pompe selon l'une quelconque des revendications 1 à 3, caractérisée en ce que les membranes sont constituées d'un matériau élastomère.
5. Pompe selon l'une quelconque des revendications 1 à 4, caractérisée en ce que les surfaces de pression sont des surfaces sensiblement sphériques.
6. Pompe selon l'une quelconque des revendications 1 à 5, caractérisée en ce qu'elle est immergée dans un réservoir pour gaz de pétrole liquéfiés.
7. Pompe selon l'une quelconque des revendications 1 à 6, caractérisée en ce que le piston est entraîné au moyen d'un excentrique.
8. Procédé d'injection de carburant dans la chambre de combustion d'un moteur de véhicule, caractérisé en ce qu'il consiste à injecter en phase liquide un gaz de pétrole liquéfié dont la pression d'injection est obtenue au moyen d'une pompe telle que revendiquée dans l'une quelconque des revendications 1 à 7.
